Questions From Users of the Manual

Q: If a product name appears in all caps in a company’s product literature (with or without a trademark symbol or registered symbol), must the editor retain the all caps in a journal article? Companies use caps for graphic impact or emphasis, but caps can be distracting and can make the text difficult to read. Would it be acceptable to substitute only an initial cap for an all-cap product name, particularly if the product is the main subject of the manuscript and occurs frequently?

A: Our journals do not require use of the trademark symbol (™) or the registered symbol (®) as the use of the initial cap frequently used on proprietary names indicates the proprietary nature of the name (see 5.6.16, Legal and Ethical Considerations, Intellectual Property: Ownership Access, Rights, and Management, Trademark). There are exceptions to the use of the initial cap (eg, pHisoHex; see section 10.8, “Intercapped” Compounds) and in these cases, as in all others, we advise using the name according to the presentation of the legal trademark. To avoid a plethora of caps—which certainly can be distracting—we would suggest varying the way in which the product is referred to (eg, “this product,” “it”) as long as the meaning remains clear.

Q: Your manual indicates that references should be numbered consecutively with arabic numerals in the order in which they are cited in the text. But what about the distinction between references cited in a range and references cited individually? If an author cites references 1 through 5, does this count as only the citation of reference 1, as the first number in the range, or does it count as citation of all 5 references included in the range?

A: It matters not if the references are cited as part of a range or cited individually. Even if a reference is cited as part of a range, when any one of those references is cited later, it retains the same reference number. This is not specifically stated in the Manual and, perhaps wrongly, we assumed that it would be understood. Thank you for allowing us to clarify this point.

Q: Convention seems to be to use the leading zero in P values, but why is this necessary since P cannot be greater than 1?

A: JAMA and the Archives Journals do not use a zero to the left of the decimal point, since statistically it is not possible to prove or disprove the null hypothesis completely when only a sample of the population is tested (P cannot equal 1 or 0, except by rounding). If convention dictates otherwise, we are unconventional!

Q: I have been unable to find specific rules on the use of nonbreaking hyphens and spaces. Do you have any suggestions for the correct and preferred use of nonbreaking hyphens and spaces?

A: You are right. We do not have any section devoted to this. However, there is information about line breaks scattered throughout the Manual. For example:

On page 29 (section 1.20.4), there is information on how to break an e-mail address. The same guidelines apply to breaking URLs.

On page 646 (section 15.6.4), there is information on breaking long karyotypes.

On page 910 (section 21.5), there is information on breaking long formulas.

There may be other instances like this scattered throughout the Manual where specific guidance is needed. However, individual publishers or clients may have their own preferences that require attention when editing material for their publications.

Q: I am working on a manuscript in which one of the authors has listed the degree MAS (Master of Advanced Studies). This abbreviation is not included in the Manual. Is it acceptable?

A: This is a perfectly acceptable abbreviation. We simply did not have space to list all possible degrees and their abbreviations in the Manual and attempted to list some of the more common ones.—Cheryl Iverson, MA
